alt Hacker News> We know how neural nets work. We don't know how a specific combination of weights in the net is capable of coherently asking questions asked in a natural language, though.
these are the same thing. the neural network is trained to predict the most likely next word (rather token, etc.) — that’s how it works. that’s it. you train a neural network on data, it learns the function you trained it to, it “acts” like the data. have you actually studied neural networks? do you know how they work? I’m confused why you and so many others are seemingly so confused by this. what fundamentally are you asking for to meet the criteria of knowing how LLMs work? some algorithm that can look at weights and predict if the net will output “coherent” text?

not sure what this is supposed to mean
It's like you're describing a compression program as "it takes a big file and returns a smaller file by exploiting regularities in the data." Like, you have accurately described what it does, but you have in no way answered the question of how it does that.
If you then explain the function of a CPU and how ELF binaries work (which is the equivalent of trying to answer the question by explaining how neural networks work), you then have still not answered the actually important question! Which is "what are the algorithms that LLMs have learnt that allow them to (apparently) converse and somewhat reason like humans?"
